TRANSMISSION MECHANISM.

I Application filed August 6, 1915. Serial No. 44,093.

To all whom it may concern Be it known that'I, JAMns GUTHRIE, a citizen of the United States, residing at- Jackson, county of Jackson, State of Michigan, have invented certain new and useful Improvements in Transmission Mechanisms, of which the followingis a specification;

This invention relates to improvements in transmission mechanisms.

The main Objects ofthis invention are: First, to provide ina motor vehicle an improved transmission. mechanism and starting motor mounting. Second, to provide in a motor vehicle an" improved driving connection for the starting motor. Third, to provide in a motor. vehicle an improved transmission gear casing and mounting which may be readily assembled in the. ve-

' hicle and conveniently disassembled to afford access to the.partscontainedtherein. Fourth, to provide a structure of the class described, which is simple andv compact in structure and also simple'and eeonomicalinits parts. Fifth, to. provide me transmission mechanism for motor vehicles an improved speedometer driving connection.

Further objects, andv objects relating tostructural details, will definitely appear from the detailed description to follow.

I accomplish the "objects of my invention by the devices and means described in the followingspecification. I V

The invention. is clearly defined and pointed out in the claims.

A structure which is Ea preferred embodiment of my invention is clearly illustrated in the accompanying drawing forming'a part of this specification, in which:

In the drawing similar referencecharac-l ters refer to similar parts throughout i the 60. several views, and the sectional. viewsiaresf taken looking in the direction of the. little arrows at the ends of the section lines.

Referring to the drawingspl represents member are hangers 2 for theyoke-like'su'p port member 3. 'The support member 3 is; provided with arms 4 at its ends terminating in bear ngs 5 to receivethe pins 6 carriedby the hangers 2 which are forked at? tore-1. 701 eeive the pins. The pinsare retainedby l i the cotters 8. i if i The support member 3 is provided with with a bearing 11 having a-bushing 12. 1 011-1 t the rear side ofthesupport 3 -I m'ount" gear box or casing 13 having: a bearin,v 7 provided with a bushing 15;.and a bearing". 16 provided with a bushing 17. The hearing 14 s alined withthe' bearing ,9 of the: sup-jlio' port, while the bearing l6is a-lined with the bearing 11 of the support. I a 1 The gear casing is removablyseeuredlto, the support by means of the bolts l8,.lthe support and easing being suitably flanged .8 to receive these bolts. On the reareii'd of: the gear casing I mount the propeller shaft" housing member 19, the same being secured to the gear casing bv the bolts 20. This propeller shaft housing member is adapted to receive the frpnt end of the propeller shaft 1,, tube, which is not shown in the drai ving; p

The joint between the gear casing andthe.

support member is preferably providedwith 1 The driving member 22 is arranged in the bearing sand, provided with a starting gear 23 at its front '1 The engine-or power shaft (not shown) is" 09 connected to the driving inember 22-through the universal joint, designated generally by. the numeral 25, which is alined with 'the pivots 6 of the support member. Asfthe structural details of this joint form no part; of my present invention I do not describe the same herein. p

The side or driving transmission shaft-26 T is disposed with one end in the bearing 11 of the support member and the other in the elined bearing 16 of the geer casing.

.01 this shaft 26 is e gear 27 meshing with driven transmission shaft 31 and the driv-' the gear 2st on the driving member and selective gears 28, 29 and 30.

The driven transmission shaft 31 has gears 32 and spline'd thereon to be shifted into mesh with the gears 28 and 29, the gear 32'being also adopted to be shifted into the' 'i'everse gear 34. The sheftill is dis: posed with its front end in the bearing 35 in the driving member which is provided with a thrust ball 36. (see Fig. 11). The

ing member may be connected'by the clutch 37, one member of which is on the gear 33 jand the other on thegeor 2%, a common jaw clutch being indicated. This clutch is engaged and the gears 32 and shifted by means of the shifting rod 38 supported at v bne side of the transmission shaft for 1on-' gitudinel movement and provided with -'erms 39 engaging the gears The shifting r0d 38 is provided-with a lever connection -10, the shifting lever however, .not being illustrated,

Onthe rear end of the transmission shaft 31 is coupling sleeve l2 for the propeller, shaft the sleeve being arranged in. the

bearing l5. This-sleeveis squared or otherwise shaped internellylto receive the similarly shaped. ends of the propeller and the driving transinissioi r shafts which are arranged in the sleeve to abut, as shown in Fig. II lhe' n'opeller shaft is secured against longitudinal movement in the con-- pling by means of the pin 4A (see Figs. 11 and VT). This pin is arranged through the sleeve and retained by the ring which embraces the coupling sleeve and fits against the shoulder 46 thereon. A washer 417 is arranged on the outside of the ring and is supported by the shoulder 48 in the propeller shaft housing member 19 so that when this housing member is bolted to the gear casing the parts are retained in their assembled relation but when released they may be readily disassembled The bearings in the casing and support member are so shaped as to-fo :ilitute their lubrication.

On the rear end of the coupling sleeve 42 is a worm gear d9 meshing with the worm 50 on the speedometer driving spindle 51 'which is adopted to receive a suitable fleXi;

ble shaft (not illustrated); The inner end of the spindle shaft 51v is supported in abeeriug 52 while its outer end is supported in a bearing threaded into the propeller shaft housing member 19. This provides a simple and direct connection for the speech ometer to the transmission mechanism;

At one sideof the gear see ng I mount a,

starting motor comprising a. suitable casing 54 and driving shaft The motor casing is secured to thesupport memberdby the bolts 56. The driving shaft 55 of the motor is disposed through the support mem-" her 3 and provided with 21$ sprocket gesr 57. connected to the-gear 23 on he driving member 22 by the sprocket chain 58. These parts are inclosed by the housing or casing member 59 secured to' the front side of the support member 3, by the bolts (50. The. housing member 59 is provided with on eX-i. tension 61 for the joint 25 provided witlr an inturned flange 62 supporting a packing for the closure member G l on the joint, The closure member is spherically curved to coact with the gasket or packing ring 63.

The motor is preferably of the type adeptede also as a generator andhas suitable connections 65 with the storage battery ,(uot illustrated rod 66. v

With the parts thus ar'anged they are conveniently and easily, assembled. In assembling the parts the driving member is first mounted in the bearing therefor in the support. The front ends of the transmis The motor is controlled by-the sion shaft with the gears thereon are then" introdueed into the bearings provided there for in the support and driving member and" the casing slipped over the some and secured.

I have not attempted to illustrate 0r-de-' scribe various" modifications which I contemplate and which might be desirable to adapt my improvements for particular .em-

bodiments, as I believe the disclosure made will. enable those-skilledin the art to which my invention relates to embody or adapt the some as may be desired.
